BABYs CHAIR-TABLE. i

Specification of Letters Patent.

Application led September 8, 1919. Serial No. 322,570.'

T0 all whom t may concern:

Be it known that I, THEoDoRE ERNST, a citizen of theV United States, residing at Bayfield, in the county of Bayfield and State of Wisconsin, have invented certain new and useful Improvements in Babiesl Chair- Tables; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

This invention relates to chairs, and more specically to an improved babys chairtable and support therefor.

One object of the invention is to provide an improved device of this character including the table and a track therefor, the table being movably secured to the track in such relation that it may be moved from the front to the rear portion of the chair without being disconnected from the chair.

Another obj ect of the invention is to provide an improved securing or holding device whereby the table may be detachably secured in its horizontal positions.V

Other objects and advantages may become apparent to personsy who read the following details of description in connection with the accompanying drawings, in which Figure 1 is a left side elevation of a portion of a chair having my improved table and table supporting means attached thereto.

Fig. 2 is a front elevation of the structure disclosed inFig. 1.

Fig. 3 is an enlarged left end elevation of my improved chair-table and a portion of the support therefor. v

Fig. 4 is a vertical sectional kview along the line 4--4 of Fig. 2. l,

Fig. 5 is an enlarged vertical sectional view substantially along the line 5 5 of Fig. 1, the table being shown in dotted lines in its raised position.

Fig. 6 is a horizontal sectional view along v the line 6-6 of Fig. 1.

Fig. 7 is a view somewhat similar to Fig. 1, but illustrating a .modified form of the invention. v Fig. 8 is a view somewhatsimilar to Fig. 3, but illustrating the invention according to the modification shown in Fig. 1.

Fig. 9 is a view somewhat similar to Fig. 4, but showing the details of construction in accordance with said modication.

Fig. 10 is a plain view of the chair, the

back being shown in horizontal section and the table being omitted.

Fig. 11 is a fragmental, sectional detail further illustrating the vmodified form shown in Figs.'7, 8 andV 9. y

Referring to these drawingsfin detail, in which similar reference characters correspond with similar parts throughout the several views, and in which the chair 7 may be of any ordinary or improved construction, having a back 8 and arms 9,-

The invention comprises a'table-top 10, cleats 11 and 11a united with the lower rsurface of the table-top, and tracks vor supports 12 on which the cleats are normally seated. Each of the cleats 11 and 11a is provided with a flange 13 which depends therefrom, and the surfaces which extend horizontally inward fromthe flanges 13 rest on Vthe supports or rods 12 while the flanges are contiguous to the outer sides ofthe supports 12 so as to constitute guidesor abutments to prevent horizontal turning of the table whenl seated ony the ysupport '12. The lefthand flange 13 also prevents edgewise'movement of the table when in the dotted line position shown in Fig'. 5.

A staple 14 is here illustrated as one form of pivotal connection or bearing which surrounds the left-hand rod or support 12, but the invention 'is not limited to this particular form or bearing.l

On the Iright-hand cleat 11a' is secured a' locking bar 15 which is movably secured to this cleat (in the embodiment shown in Figs. 1-6) by means of a pair of strips or plates 16. A handle 17 is formed of a length of wire having its ends sharpened 'and turned parallel to one another, and these ends extend through the strips 16 into the bar 15 so as to secure the latter to the strips.

However, the invention is not limited to this specific means of securing the bar-15 and strips 16 together. The cleat 11a is formed with countersunk apertures 18, and the strips 16 are provided with corresponding Yapertures through which extend a vpair of bolts 19 which are providedwith nuts at their inner ends. Springs 20 are seated between the nuts and the bottoms of" the countersunk apertures, and these springs and nuts coperate with the strips`16 for holding the lockino bar 15 yieldingly in its locked position. Supplemental screws 21 extend through the strips 16 into the cleat Patented Aug. 31, 1920.

11a, and the heads of these screws v21 are i preferably'spaced from the strips 16 to permit the outward movement .of the bar 15 whichis necessary forV unlocking the table from the right-hand rod or support 13.

Although the supports 12 are preferably of counterpart construction for the sake of uniformity and convenience onlyv the left'- hand one of these supports is essentially a track, and this track (in the embodiment shown in Figs. 1-6') is formed of a single length of rod which `has its front end enlarged at22, its rear end portion beingrbent into U-shape, and one arm of the U-shaped rear portion of the rod being embedded in anpaperture indicated at 23 in Fig. 6. v The U-shaped portion of the track 12 extends a considerable distance vrearward of the chairback 8, andthe middle portion of the track is spaced a considerable distance from the left side of the chair, its front end being secured to the chair by means of a stud 24.

VThe operation is as follows: Y Y

When. a baby is inthe chair, the table is in the horizontal position shown in Fig. 1, and the locking bar 15 is disposed under the supporting rod 13. i When it is desired to remove the baby from the chair, or When y the table is not needed in the front position,

rests upon the righthand support 12, it be-V ing understood that the bar 15 has its inner edge beveled so that it acts as a latch in passing downward beyond the support 12. Similarly, when it is desired to move the table from the kdotted line position (shown in Fig. 6) to the full line position, it is unlocked from the support 12 by means of the handle 17, swung upward until it reaches its4 vertical position, and it is then slid forward Y implied and claimed.

y along the track 12 until it reaches its for-l wardmost position. For securing the table in the forwardmost position, a pair of studs or shoulders 25 are provided to abut against opposite sides `of the right-hand supporting stud 24, and suitablecavit'ies or depressions are provided to receive the enlarged end portions 22 of thefsupporting rods 12, so that these enlarged portions also provide keepers -or detaining' means whereby the table is retained in its normal relation to the f Y thoseof Figs. 1-6. This modified form of erally across the back of thel chair and sup ported by the brackets 30, as illustrated in Figs. 7 and 10, the front ends of the rod 12a being supported by studs 24 similar to the table support comprises a track for the table, as in the previously described embodiment of the invention, and in addition, the middle portion .of the U-shaped rod eifeo Y tually braces and stiffens the structiilre so as to eliminate the probability of sagging of the parallel supportingelements of this rod. The combination formed by the brackets and rod 12a also forms a convenient handlev for use in moving the chair.

Referring moreparticularly to Figs. 8, 9 and 11, it will Vbe 'seen that the cleat 11a Vis formed with countersunk apertures .18, as previously described, but in lieu of the 'previously described elements 16, 17, 19, 2O and 21, springs 2Oa are provided in each of the` apertures 18, and each of these springs is provided with alwire extension 2Gb which has its ends extendedinto the'bar 15 as indicated at 20C, Ythe portions of the wire between each spring and the nearest end 20c being formed into loops which receive a handle-bar 17 a. A portion of the wire may also be looped about another portion, as indicated at 20, to increaserthe rigidity of ,95 this manipulative device. The intermediate portion of the wire is secured to the cleat 11f'L by screws 20e, Vas illustrated in Fig. 9, so that the springs 2Oa have their inner ends secured to the inner surface of the cleat 11a. 100 From the foregoing description, it will be seen that a single length of wire may be employed in forming springs 20,, the loop surrounding thefscrews 209'-, the loopsaround the handle-bar 17a, andthe end elements 105 which engage with the bar 15.

Although I have described these embodiments ofmyinvention very specifically,it is not intended to limit this invention tothese exact details of construction andarrange- 110 ment ofparts, but changes may be made within the scope-of the inventive ideas as` What I claimV as my,` invention Vis,-a
